Artery Blocking vs Rubber Bands for Internal Hemorrhoids
This trial compares two treatment methods for internal hemorrhoids that haven't improved with diet, fiber, or creams. One method blocks blood flow to the hemorrhoids using a catheter (a thin tube); the other uses rubber bands to cut off blood supply. Both are minimally invasive procedures.

Exercise Program for Heart Artery Dissection and Fibromuscular Dysplasia
This study tests whether a supervised exercise program is safe and helpful for people who have had a spontaneous tear in a heart artery (SCAD) or fibromuscular dysplasia (a condition affecting blood vessel walls). The goal is to see if exercise can improve heart health after recovery from these conditions.
Jacksonville, FloridaAges 21–65 - NCT07089576Recruiting
Study of the Arcevo LSA device for aortic arch repair
This trial tests a new device called Arcevo LSA to treat certain types of aortic arch problems, like dissections (tears) or aneurysms (bulges). It is for people who need open surgery, and the device helps fix the left subclavian artery area.

SG2918 for relapsed or refractory multiple myeloma
This trial tests a new drug called SG2918 for people with multiple myeloma that has come back or stopped responding to treatment. It aims to see if the drug is safe and possibly effective.
Zhengzhou, HenanAges 18–80 - NCT07032389RecruitingPhase 2
A single pill for heart attack recovery
This study tests a single pill that combines three heart medicines—aspirin, a blood thinner, and a statin—to see if it helps people who have had a heart attack or stent procedure. It aims to make it easier to take your daily heart medications.
Dallas, TexasAges 18 years+ - NCT07638462Recruiting
Early mobility recovery program after acute stroke
This study tests whether early movement and physical activity help stroke patients recover better mobility. You'd be in the hospital after a recent stroke, and the team would work with you on safe movement and exercises during your recovery.
Winston-Salem, North CarolinaAges 18 years+ - NCT07687576RecruitingPhase 2/Phase 3
Comparing clot removal methods for heart attack patients
This trial tests if a special device that sucks out blood clots during a heart attack is better than standard care for reducing clot size before placing a stent. It may help patients who have a large clot and a blocked artery.
Oxford, OxfordshireAges 18 years+ - NCT06327035Recruiting
Walking recovery after a recent stroke
This study follows how walking ability improves in people recovering from a recent stroke during their stay in a rehabilitation center. The goal is to better understand recovery patterns so therapy can be tailored.
Granville, NormandyAges 18 years+ - NCT06327334Recruiting
Brain-heart interaction study after cardiac arrest
This study looks at how the brain and heart interact after a cardiac arrest that leaves someone unconscious. It aims to understand these connections better, which could help improve care for future patients.
Brest, Brittany RegionAges 18 years+ - NCT06327984Recruiting
Sex hormones and inflammation in heart disease
This study looks at how sex hormones and inflammation affect chest pain and heart disease. It aims to improve care for people with coronary artery disease.
LondonAges 16 years+ - NCT06328608RecruitingPhase 2/Phase 3
PRX-102 for children with Fabry disease
This study tests a new enzyme replacement therapy called PRX-102 for children with Fabry disease. It aims to see if the drug is safe and helps manage symptoms like pain and eye or skin changes.
Phoenix, ArizonaAges 2–17 - NCT06329635Recruiting
Nicardipine via spine tube for brain blood vessel spasm
This trial tests whether giving a medicine called nicardipine through a tube in the spine (intrathecal) helps prevent or treat blood vessel tightening that can happen after a brain aneurysm rupture. It is for people who have had a specific type of brain bleed and show signs of vessel spasm.
Hefei, AnhuiAges 18–80 - NCT06330818Recruiting
Imaging study for Moyamoya disease
This study tests different brain imaging methods (MRI and PET/CT) to better understand blood flow and disease activity in people with Moyamoya disease. The goal is to learn more about the condition and possibly find new ways to see how active the disease is.
Tübingen, Baden-WurttembergAges 18–80 - NCT06331208Recruiting
Mechanisms of Lung Blood Vessel Problems in Heart Failure
This study looks at how heart failure affects blood vessels in the lungs. If you have heart failure with reduced pumping ability and need a heart catheterization, you may be able to join.
PragueAges 18 years+ - NCT06332391Recruiting
Paced heart rate increase for heart conditioning
This trial tests whether a special pacing pattern can strengthen your heart's pumping ability. You may qualify if you have heart failure with a low ejection fraction and already have a pacemaker or defibrillator with an atrial lead.
Iowa City, IowaAges 18–120 - NCT06332911Recruiting
Shockwave balloon to help place aortic stent graft
This trial tests a special balloon that uses shock waves to crack calcium in the iliac arteries, making room for a larger aortic stent graft. It is for people with a bulging aorta (aneurysm) who also have heavily calcified or narrow iliac arteries that would otherwise prevent the graft from passing through.
